LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Feb. 1 7, 1914.

Application filed. September 27, 1912. Serial No. 722,744.

To all whom it may concern Be it known that I, WILBUR H. RADFORD, a citizen of the United States, residing at Athens, in the county of Athens and State of Ohio, have invented a new-and useful Loose-Leaf Binder, of which the following is a specification.

One object of the present invention is to provide, in a perforating machine, novel means whereby the perforated sheets may be removed from the carrier and be engaged with a sheet holder.

Another object of the invention is to provide novel means for actuating the punching members.

The invention aims further, to improve, generally, devices of that type to which the present invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction, hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, Figure 1 is a front elevation; Fig. 2 is a perspective of one of the guides; Fig. 3 is a perspective view of the needle holder; Fig. 4 is an elevation showing a modified form of needle; Fig. 5 is a vertical transverse section; and Fig. 6 is a perspective of the carrier.

In carrying out the invention there is provided a supporting structure denoted generally by the numeral 1, the supporting structure comprising end plates 2 which uphold a frame denoted generally by the numeral 3. The frame 3 comprises a top plate 4, a back plate 5, a bottom plate 6 and rack bars 7 and 8, the teeth of the rack bars 7 and 8 preferably facing toward each other.

The invention further includesa punch carrying member 9 provided with rack bags 10, the teeth of which face the teeth of the rack bars 7 and 8 respectively. The punch carrying member 9 may be equipped with set screws 11 adapted to hold the punches 12 in place, the punches 12 operating through an anvil 14 which connects the end plates 2. Mounted upon the top of the anvil 14 is a stop 15, held in place adjustably for transverse movement by means of set screws 16.

A plurality of pinions 17 are provided, the pinions 17 meshing into the rack bars 10 of the punch carrying member, and into the rack bars 7 and 8 of the supporting structure. Secured to the pinions 17 are levers 18 which slant in opposite directions. The rods 19 are pivotally connected with the upper ends of the respective sets of levers 18, the rods 19 terminating at their adjacent ends in eccentric straps 20, adapted to engage the eccentrics 21 upon a shaft 22, journaled in a bracket 23 secured to the top 4 of the frame 3. A bracket 100 projects rearwardly from the back 5 of the frame 3, and may support a motor 24 which is operatively connected with the shaft 22. The shaft 22 may also carry a hand wheel 25, to the end that the punches may be operated manually, when desired. Interposed in the shaft 22 is a clutch 26 whereby the motor 24 may be disconnected.

Referring to Fig. 6 there is shown a carrier 27 provided with a longitudinal slot 28, adapted to receive a set screw 29, connected with a paper guide 30, to permit of an adjustment of the paper guide 30 from one end of the carrier 27 toward the other. On one edge, the carrier 27 is equipped with notches 28. Arched springs 31 are secured to the under face of the carrier 27, adjacent its ends, the springs 31 extending transversely of the carrier. Pins 32 are secured at their lower ends to the lower arms of the springs 31, the pins 32 being adapted to reciprocate in openings 33 formed in the carrier 27. Compression springs 34 surround the pins 32 and abut against the lower and upper arms of the springs 31. The springs 31 are mounted to slide on guides 35 secured to the end plates 2, each guide 35 being pro-- vided at one end with a stop 36 and at the other with a stop 37.

Guides 38 are secured to the plates 2, ad jacent the. lower ends of the plates, the guides 38, as shown in Fig. 2, taking the form of angle bars. Set screws 39 operate in vertical slots in the end plates 2, the set screws 39 being connected with the vertical flanges of the guides 38. In the horizontal flanges of the guides 38 are longitudinal slots 41 adapted to receive set screws 42 which engage the ends of the bar 40, con stituting a part of the sheet holder. The bar 40 is provided with a plurality of transverse, flaring notches 42. In each of the notches 42 is disposed a fixed gripping memher "l3, the same being held in place by means of the securing elements Located in each of tho notches 4:2 is a movable gripping member 1-5, the same being pivotally mounted as indicated at 46. One end of a screw st? is mounted in the gripping member 43, the screw 1-7 passing through the grippii member 15 and being threaded at its outer end as indicated at 4-8, to receive a wing nut -19. In the adjacent faces of the gripping members 4:5 and d3 are mating notches 50, adapted to receive a needle 51.

The operation of the device as hereinbefore described, is as follows :The sheet carrier 2? is mounted in place upon the guides 35 and is pushed away from the operator until the ends of the lower arms of the springs 31 abut against the stops 3?. By this operation, the notches 28 in the carrier 27 will be positioned below the punches 12 and above the openings in the anvil 1-1. The sheets of paper which are to be punched are placed upon the carrier 27, and pushed rearwardly until they abut against the back stop 15, the sheets of paper being constrained against movement longitudinally of the carrier 27, by means of the paper guide 30 which may be adjusted along the carrier. VJ hen the punches 12 are operated in a manner to be set forth hereinafter, the sheets of paper which rest upon the carrier 27 will be perforated. After the sheets of paper have been perforated in the manner hereinbefore set forth, the carrier 27 is drawn toward the operator until the ends of the springs 31 abut against the stops 36. By this operation, the holes which have been fashioned in the. sheets of paper will be lo cated directly above the needles 51. Manual pressure is then applied to the sheets of paper, adjacent their perforated edges, whereupon the springs 31 and the springs 34 will be put under compression, one edge if the carrier :27 and the sheets of paper being lowered until the needles 51 pass through the openings in the paper. That edge of the carrier which is adjacent the operator, is thenelevated, the carrier being withdrawn over the upper edges of the stops 36. Thereupon, the perforated sheets of paper will drop downwardly to the bottom of the machine, the sheets of paper being held in place by the needles 51. The carrier 27 is then replaced and is pushed into abutment with the stops 37, whereupon the operation l')G1Qli1l)Gf( 1 described, may e repeated. By manipulating the set screws 39 in the slots 60, the holder, comprising the bar 10 and attached parts, may be raised or lowered. By manipulating the set screws 4-2 in the slots -11 of the guides 38, the position of the bar 4.0 may be adjusted transversely of the machine, the positions of the needles 51, f course. being shifted accordingly.

.iiie needles 51 may be mounted between the gripping members 43 and by manipulating the wing nuts 4-9, it being possible to remove one or more needles at any time. withoutinterfering with the operation of the machine. lVhen rotary movement is imparted to the shaft 22, either through the medium of the motor 2%, or through the medium of the hand. wheel 25, the eccentrics 21 will be actuated, the same engaging the eccentric straps 20 and moving the bars 19 in opposite directions, the levers 18 being actuated, the same imparting rotary movement to the pinions 17. The pinions 17, engaging the fixed rack bars 7 and 8 of the supporting structure, and engaging the movable rack bars 10 which are connected with the punch holder 9, will impart vertical reciprocatory motion to the punch holder, as will be understood readily.

It. is to be understood that the needles which are mounted between the gripping or clamping members 43 and 45 may be fashioned in any desired manner.

As shown in Fig. i, one of the needles is indicated by the reference numeral the same being notched for sewing, as indicated at 53.
